Description

According to the present invention, a connector cap that is attached and coated on the connection end face side of the connector to protect the connection terminal of the connector from water and dust, and the connector cap are attached to a connector provided on the terminal of the conductive path. The present invention relates to a method of winding a conductive path on a drum, in which the conductive path is wound around the body of the drum.

As a conventional connector cap, a cap formed of an insulating synthetic resin and provided with a substrate and a peripheral wall formed in a tubular shape and having one end in the axial direction continuous with the peripheral edge of the substrate is known. (See, for example, Patent Document 1). The conventional connector cap has an opening at the end opposite to the side on which the substrate is formed in the axial direction. An insertion portion communicating with the opening is formed inside the peripheral wall. The insertion portion is formed so that the connection end face side of the connector can be inserted, and the inner surface of the peripheral wall abuts on the outer surface of the connector in the inserted state on the connection end face side.

By the way, a conductive path (for example, a cable or a branch cable) provided with the above connector on a terminal in the longitudinal direction is packed and shipped in a drum winding like a general cable because the product strip length is relatively long. ing.

Here, in the conventional connector cap, the inner surface of the peripheral wall of the cap is in contact with the outer surface of the connector in a state where the connection end surface side of the connector is inserted into the insertion portion. Therefore, when a load is applied to the outer surface of the peripheral wall of the cap due to drum winding during manufacturing, the weight of the cable during transportation or storage, or an external load, this load is directly applied to the outer surface of the connector.

Further, according to the drum winding method of the cable 2 of the present embodiment, the terminal is attached to the body of the drum with the connector cap 1 of the present embodiment attached to the connector 3 provided at the terminal of the cable 2. Since the cable 2 is wound as the winding start point, even if a load due to the weight of the wound cable 2 is applied to the connector cap 1, this load is distributed and no external force is directly applied to the outer surface 13 of the connector 3. .. In this way, when a load is not directly applied to the outer surface 13 of the connector 3 and an external force is applied to the outer surface 13 of the connector 3 by distributing the load, the connector cap 1 of this embodiment is attached to the connector 3. The load capacity is improved as compared with the case where the cable 2 is wound around the body of the drum without being attached to the connector (with the conventional connector cap attached to the connector 3).

When the contact point with the inner surface 50 is illustrated by the quotation marks 53 and 54, the side connecting the contact points 51 and 52 and the side connecting the contact points 53 and 54 can be viewed from either the X-axis direction or the Y-axis direction. It is formed in a shape that does not overlap.

According to the connector cap 41 of this embodiment, the standing angle of the rib 46 (the angle of inclination of the line segment L8 with respect to the line segment L7 shown in FIG. 10) is in the extending direction of the outer surface 49 of the first protection portion 45. Since it is provided so as to be offset from the orthogonal direction (line segment L9 shown in FIG. 10), when a load is applied from directly above the rib 46, the cushioning portion 48 can be deformed so that the load does not concentrate on the rib 46. can.

Next, the effect of this embodiment will be described.
As described above with reference to FIGS. 9 and 10, according to the present embodiment, the same effects as those of the first and second embodiments are obtained.

In addition, it goes without saying that the present invention can be modified in various ways without changing the gist of the present invention.

In the above description, the connector cap 1 in the first embodiment has a cross section orthogonal to the axial direction formed in a circular shape in both the first protective portion 5 and the second protective portion 7, and the connector cap 21 in the second embodiment and the connector cap 1 in the second embodiment. The connector cap 41 in the third embodiment has a non-circular (rectangular) cross section orthogonal to the axial direction in both the first protective portion 25 (first protective portion 45) and the second protective portion 27 (second protective portion 47). ), But the configuration is not limited to this, and the following configuration may be used.

That is, although not particularly shown, the connector cap of the present invention has a circular cross section orthogonal to the axial direction of the first protective portion and a non-circular cross section (for example, rectangular) orthogonal to the axial direction of the second protective portion. ) May be formed. Further, although not particularly shown, the connector cap of the present invention has a non-circular (for example, rectangular) cross section orthogonal to the axial direction of the first protective portion and a cross section orthogonal to the axial direction of the second protective portion. It may be formed in a circular shape.
